It's hard to find happiness after success if the goalposts of success keep changing.

We not only need to work happy, we need to work at being happy.

By changing our mindset and habits, we can actually dramatically change the course of life, improve intelligence, productivity, improve the quality of our lives, and improve every single education and business outcome.

Happiness is not the belief that we don't need to change; it's the realization that we can.

Happiness is the joy we feel striving after our potential.

The greatest competitive advantage in our modern economy is a positive and engaged brain.

You can study gravity forever without learning how to fly.
